On 3-coloured tournaments

We (re-)prove that in every 3-edge-coloured tournament in which no vertex is incident with all colours there is either a cyclic rainbow triangle or a vertex dominating every other vertex monochromatically.

The Cape Coloured People*

and the spleen usually becomes bigger. The pressure in the portal vein and its radicles may rise from the normal 8 to 11 mm. Saline to as much as 50 mm. Saline. Anastomotic channels between the portal and the systemic systems open up. The veins round the lower end of the oesophagus are the most important of these anastomotic channels and become enormously dilated. They bleed readily and massive...

The Coloured Quantum Plane

Abstract. We study the quantum plane associated to the coloured quantum group GL q (2) and solve the problem of constructing the corresponding differential geometric structure. This is achieved within the R-matrix framework generalising the Wess-Zumino formalism and leads to the concept of coloured quantum space. Both, the coloured Manin plane as well as the bicovariant differential calculus ex...

On the Abstraction of Coloured Petri Nets

This paper considers the appropriate properties for abstract net components in the Coloured Petri Net formalism. In doing so, it attempts to maintain the duality between places and transitions which is so foundational to Petri Net theory. It also defines what it means to execute the net at an abstract level.
